Description

Technical Field

[0001] The utility model relates to the technical field of ice making equipment, in particular to a movable ice blade and an ice crushing assembly and an ice crushing device using the same. Background Art

[0002] Refrigerators with ice-making functions on the market all have multiple components such as an ice-making device, an ice storage bucket, an ice-crushing motor, and a dispenser to form a complete set of ice-making functions. The ice-making machine is responsible for making ice cubes until the ice storage bucket is full of ice cubes. The ice storage bucket mainly contains a large volume to store ice cubes, and a matching ice-crushing blade assembly. The ice-crushing blade assembly can cooperate with the ice-crushing motor and be driven by the ice-crushing motor to crush the larger ice cubes made by the ice-making machine. These ice-crushing blade assemblies on the market generally consist of multiple moving ice blades with different installation angles and multiple fixed ice blades. The moving ice blade is installed on the ice blade shaft and rotates with the output end of the ice-crushing motor, while the fixed ice blade is fixed.

[0003] The movable ice blade in the refrigerator ice crushing device generally used in the prior art is mostly designed as an integral flat structure from the perspective of durability and cost, that is, the overall outer surface between the part where the movable ice blade and the ice blade shaft are installed and the part where the movable ice blade specifically crushes ice cubes is flat. For example, the movable ice blade in the ice crushing device disclosed in Publication No. CN 105423672 B, and the movable ice blade in the ice crushing device of the ice maker disclosed in Publication No. CN 217154622 U. In the process of ice crushing, the movable ice blade under this structure is subjected to most of the resistance borne by the cutting surface of the movable ice blade, and is not easily deformed, thereby increasing the service life of the ice crushing device.

[0004] However, based on actual use and research, it was found that the blade surface of the moving ice blade of the above structure does not have the function of pushing the ice cubes. Often only the first section of the moving ice blade that first contacts the ice cubes takes on most of the ice-crushing work, resulting in low ice-crushing efficiency and increased waiting time for users to get ice.

[0005] Therefore, from the perspective of improving ice crushing efficiency, it is necessary to further optimize the structure of the moving ice blades. Utility Model Content

[0017] In an optional implementation of the present invention, the ice crushing surface of the first blade portion and / or the second blade portion is provided with continuously distributed serrations.

[0018] In an optional implementation of the present invention, the movable ice blade includes the mounting plate and at least two of the ice breaking plates evenly distributed on the circumferential side of the mounting plate.

[0019] In an optional implementation of the present invention, at least two of the crushing plates are spirally arranged relative to the mounting plate, so that all the crushing plates and the mounting plate together form a propeller blade-shaped structure.

[0027] The ice crushing device of the utility model is realized in this way:

[0028] An ice crushing device comprises an ice storage box and an ice crushing assembly arranged in the ice storage box.

[0029] By adopting the above technical scheme, the utility model has the following beneficial effects: the movable ice knife of the utility model and the ice crushing assembly and ice crushing device using the same, through the design of each crushing plate where the plane where the first blade portion and the plane where the second blade portion are located are respectively deflected relative to the plane where the mounting plate is located to form an angle, so that the first blade portion and the second blade portion of the movable ice knife can guide the ice cubes while crushing the ice.

[0039] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0040] Embodiment 1:

[0041] See also Figures 1 to 8 As shown, this embodiment provides a movable ice blade, which is suitable for a refrigerator with an ice maker. Its general structure includes: a mounting plate 1 and at least one blade crushing plate 2 connected to the mounting plate 1. The mounting plate 1 here is convenient for matching with the ice crushing device in the ice making and pushing, and a connecting hole 11 is formed on the mounting plate 1, and the connecting hole 11 is used to connect with the ice blade shaft 3 in the ice crushing device.

[0042] Specifically, in more detail, each crushing blade 2 includes a plate-shaped body, and a first blade portion 21 and a second blade portion 22 formed on the plate-shaped body and arranged opposite to each other. Specifically, in conjunction with the accompanying drawings, the plane where the first blade portion 21 and the plane where the second blade portion 22 are located are respectively deflected relative to the plane where the mounting plate 1 is located to form an angle α; and the plane where the first blade portion 21 and the plane where the second blade portion 22 are located are respectively deflected in opposite directions relative to the mounting plate 1 along the axial direction of the connecting shaft 11. Figure 3 As shown, plane A may be the plane where the first blade portion 21 is located or the plane where the second blade portion 22 is located, and is deflected relative to plane B where the mounting plate 1 is located to form an angle α.

[0043] Furthermore, 0°<α≤30°. For the crushing blade 2 with this deflection angle, it can not only guide and push the ice cubes 4 during the ice crushing process, but also take into account the requirements of its use strength, thereby reducing the probability of deformation during long-term use.

[0044] In a preferred implementation case here, the deflection angle of the plane where the first blade portion 21 is located relative to the mounting plate 1 is the same as the deflection angle of the plane where the second blade portion 22 is located relative to the mounting plate 1. Based on this, it means that the crushing plate 2 is no longer integrally located on a plane relative to the mounting plate 1, but exists in two different planes. Under this design, even if only one crushing plate 2 is designed for each movable ice blade 5, when the movable ice blade 5 is used in a specific ice crushing device, it can form a functional area with an adjacent pair of fixed ice blades 6 that can both crush ice and guide and push ice cubes 4. In other words, the movable ice blade 5 under this design can simultaneously take into account the coordination effect with the adjacent pair of fixed ice blades 6.

[0045] Here, for the mounting plate 1 and the blade-breaking plate 2 included in each movable ice blade 5, it is preferred to adopt an integrally processed structure, and in terms of thickness, the thickness of the optional blade-breaking plate 2 can be selected to be consistent with the thickness of the mounting plate 1. Of course, in order to compensate for the deformation problem that may occur in the long-term ice crushing process due to the deflection of the blade-breaking plate 2 relative to the mounting plate 1, the thickness of the blade-breaking plate 2 can also be designed to be greater than the thickness of the mounting plate 1, thereby improving its anti-deformation effect. The above situations all meet the use requirements of this embodiment, and this embodiment does not make an absolute limitation on this.

[0046] In an optional implementation, the first blade portion 21 and / or the second blade portion 22 are provided with continuously distributed saw teeth 23 on the crushed ice surface. Here, when the first blade portion 21 and the second blade portion 22 are both designed with saw teeth 23, the structures of the saw teeth 23 on the first blade portion 21 and the second blade portion 22 can be completely the same or different, and the difference here can be reflected in the shape of the saw teeth 23, and can also be reflected in the size of the saw teeth 23, and this embodiment does not make an absolute limitation on this.

[0047] On the basis of the above structure, it should be noted that, in order to improve the ice crushing efficiency, each movable ice blade 5 includes a mounting plate 1 and at least two crushing plates 2 evenly distributed on the circumferential side of the mounting plate 1. When the movable ice blade 5 here uses more than two crushing plates 2, the frequency of cutting the ice cubes 4 can be increased every time the movable ice blade 5 rotates one circle, thereby improving the ice crushing efficiency.

[0048] For example, each movable ice blade 5 includes three or four crushing plates 2. In this case, the three or four crushing plates 2 are spirally arranged relative to the mounting plate 1, so that all the crushing plates 2 and the mounting plate 1 together form a propeller blade structure. When the movable ice blade 5 uses an even number of crushing plates 2, such as four, each pair of crushing plates 2 located on both sides of the center of the connecting hole 11 is arranged in a central symmetrical structure. Under such a structure, the structure of the entire movable ice blade 5 is more balanced, and the ice crushing force generated on the ice cubes 4 during the ice crushing process is also more stable.

[0049] In addition, it is necessary to explain that the approximate shape of the breaking plate 2 used by the movable ice blade 5 in the present embodiment may be, for example, roughly rectangular or roughly sickle-shaped or other shapes that are maturely used in the prior art. The present embodiment does not make an absolute limitation on this, nor does it enumerate them one by one. For the breaking plate 2 of the present embodiment, it can be understood as the movable ice blade 5 that is maturely used in the prior art. On this basis, each breaking plate 2 is integral or the two blade parts are respectively deflected at a certain angle relative to the mounting plate 1 to meet the use requirements of the present embodiment.

[0050] In summary, for the movable ice blade 5 used in this embodiment, the first blade portion 21 and the second blade portion 22 can play a role in guiding the ice cubes 4 while crushing the ice.

[0051] Embodiment 2:

[0052] See also Figures 1 to 8 As shown, based on the movable ice blade 5 of embodiment 1, this embodiment provides an ice crushing assembly, comprising: an ice blade shaft 3 and a plurality of fixed ice blades 6 and a plurality of movable ice blades 5 arranged in the axial direction; wherein the ice blade shaft 3 is connected to the connecting hole 11 of the movable ice blade 5, so that the movable ice blade 5 has the freedom to rotate synchronously with the ice blade shaft 3. It can be understood that, in combination with the conventional and mature ice crushing assembly, although the fixed ice blade 6 here is sleeved on the ice blade shaft 3, the fixed ice blade 6 will not rotate synchronously with the ice blade shaft 3.

[0053] Furthermore, multiple fixed ice blades 6 and multiple movable ice blades 5 are arranged alternately in sequence, so that a movable ice blade 5 is provided between every two adjacent fixed ice blades 6; under this structure, when the ice blade main shaft rotates, the movable ice blade 5 and the fixed ice blade 6 shear against each other to break the ice cube 4 into ice particles, and in combination with the multiple movable ice blades 5 distributed along the ice blade main shaft, the ice cube 4 can be pushed to the vicinity of the next section of the movable ice blade 5 under the guidance of one movable ice blade 5, and then chopped again by the next section, and the ice cube 4 is pushed in sequence in this way, thereby improving the circulation efficiency of the ice cube 4 between different movable ice blades 5, thereby improving the ice crushing efficiency and reducing the user's waiting time for taking ice.

[0054] In addition, it should be noted that the gaps formed between each movable ice blade 5 and the two adjacent fixed ice blades 6 are smaller than the minimum size of the ice cube 4. Since the planes where the first blade portion 11 and the second blade portion 12 of the movable ice blade 2 of the movable ice blade 5 in this embodiment are located are deflected in opposite directions relative to the plane where the mounting portion 1 is located, and the deflection angle of the plane where the first blade portion 21 is located relative to the mounting plate 1 is the same as the deflection angle of the plane where the second blade portion 22 is located relative to the mounting plate 1, in this case, when the mounting plate 1 is parallel to the fixed ice blade 6 on the ice blade shaft 3, the first blade portion 21 or the second blade portion 22 of each movable ice blade 2 and the two adjacent fixed ice blades 6 will form two gaps a1 and b1. For example, in combination with the example of the accompanying drawings, a1 is smaller than b1, and the gap a1 here is smaller than the minimum size of the ice cube 4. It should be noted here that, in an optional case, the conditions formed between each movable ice blade 5 and the adjacent fixed ice blade 6 are the same, so the gap conditions formed between each movable ice blade 5 and the adjacent fixed ice blade 6 are also the same.

[0055] The understanding about the minimum size of the ice cube 4 here is as follows: since the multiple moving ice blades 5 realize the cutting and crushing effect of the ice cube 4 in sequence, for the ice crushing assembly used in the ice crushing device includes the multiple moving ice blades 5 arranged in sequence, the sizes of the ice cubes 4 to be crushed by the adjacent moving ice blades 5 are different. Therefore, the ice cube 4 is crushed by the previous moving ice blade 5 and then crushed by the next moving ice blade 5. Therefore, in this embodiment, the gap formed between each moving ice blade 5 and the adjacent fixed ice blade 6 is smaller than the size of the ice cube 4 to be crushed by the last moving ice blade 5 among the multiple moving ice blades 5. At this time, the corresponding size of the ice cube 4 to be crushed after being crushed by the previous multiple moving ice blades 5 is the smallest.

[0056] In summary, for the crushing assembly of the present embodiment, when the ice blade shaft 3 rotates, the movable ice blade 5 can smoothly push the ice cube 4 into the next movable ice cube 4 adjacent to the movable ice cube 4, thereby preventing the ice cube 4 from being stuck between the adjacent fixed ice blade 6 and the movable ice blade 5, i.e., effectively ensuring the pushing efficiency of the ice cube 4 between different movable ice blades 5.

[0057] Embodiment 3:

[0058] Based on the ice crushing assembly of Example 2, this embodiment provides an ice crushing device, including: an ice storage box and the ice crushing assembly of Example 2 arranged in the ice storage box. The ice storage box here can optionally adopt a mature structure in the prior art. This embodiment only optimizes the structure of the movable ice blade 5 on the ice crushing assembly used therein. This embodiment does not improve other structures and implementation principles, so the specific details are not repeated.

[0059] The above specific embodiments further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention.
